I'm as mystified as you as to why it first worked, and now it doesn't. I looked
at the ticket and it seems like much of the same. I have one multiplex (out of
six) where the data is just plain garbage. I filled in the missing netid,
transportid and put reasonable-looking defaults in some of the other
wierd-looking fields. I now don't get the error message, but I also still don't
get any of the channels :( There is also /no/ attempt by the channel scanner to
update this record at any point, whatever I try.
My only option, I think, is to use one of the other multiplexes and base my
scans around that. That means clearing out all the channels and starting again
from scratch, something I did only a week ago, and something I'll have to do
again on the 22nd Feb :( If I don't I lose all the BBC channels.
Hmm. It seems that this one multiplex is transmitted on a different antenna to
the other five (on the same mast). I wonder if something's set up differently?
